Asia Based PARS: Guide for the Frequency Domain Spectroscopy Measurement

for transformer bushing – Dr. Jun Deng Lead Exits PAR from CSEE PE/TR reviewed a published standard form CSEE who was looking

for potential adoption and/or revision. Initially declined Sponsorship however there CSEE requested a

second review for Revision which was discussed extensively.However only one clause, 6.3 was seen to have potential interest. SA has communicated with CSEE that PE/TR is not interested in

revision since only one clause had potential. CSEE has a new proposal will be discussing it at AdCom (3/25/18)

Recordings of the proceedings of standards development meetings IEEE-SA applies restrictions on recording the proceedings of IEEE standards

development meetings. Restrictions include, but are not limited to, the usage of audio recording, video recording, and photography by participants or observers.

An officer of the Working Group or one of its subgroups, unless prohibited by the P & P of the Sponsor or Working Group, is permitted to record, via either audio or slideshow recording only, the proceedings of an IEEE standards development meeting for which he or she is responsible. Recording of the proceedings by any other participant or observer, in part or in whole, via any means, is prohibited.

The Working Group or subgroup officer shall use the recording exclusively for the purpose of generating minutes. The officer shall not copy or further distribute the recording. Once the meeting minutes have been prepared, the officer shall delete the recording.

Any IEEE standards development meeting may be recorded for preparation of the meeting minutes as described above. If recording is expected to occur these apply:– The intent to record for preparation of the meeting minutes shall be noted on the

distributed meeting agenda. – At the beginning of the meeting, the Chair or designee shall announce the intent

to record the meeting and shall notify participants that remaining in the meeting is an agreement to be recorded.

– The fact of the announcement to record the meeting shall be included in the meeting minutes.

IEEE-SA Updates (Cont’d)Expiring PARS:

• 2018 - 13 PARS are on the Dec. • 2 PARs on the April. RevCom Agenda.

6 are in Sponsor Ballot stage5 are still in WG development stage

• 2019 -10 PARs expiring, 3 are on in Sponsor ballot stage, 5 at Draft Dev. Stage, 7 in WG Development stage

Expiring Standards in 2018• 14 Stds will become inactive , 2 do not have Active PARS

o IEEE C57.136 does not have a PAR

Expiring Standards in 2019• 7 Stds Expiring, • IEEE 57.111 and IEEE 57.121 do not have PARS

5

IEEE/IEC Adoptions IEEE-SA will no longer adopt ISO or IEC Standards, effective

immediately.

ANSI recently notified IEEE of a change to the ANSI/IEEE license agreement for the sale of National adoptions of ISO and IEC Standards (NAIS). This change is mandating that an adopted standard be labeled as a “U.S. national” standard and must include a U.S. national forward and national branding on each page. In addition, these adopted standards can only be actively marketed/sold in the U.S. This change to the ANSI/IEEE license agreement is inconsistent with IEEE-SA’s position as a developer of global standards.

IEEE-SA along with ISO and IEC are still committed to mutual collaboration. The joint development/dual logo agreements with ISO and IEC remain in place. ISO or IEC can still adopt an IEEE standard

ISO/IEC Standards can still be used as Normative References in IEEE-SA Standard as this change does not affect the use of ISO and IEC standards as normative references.

Options available to Working Groups?– Working groups are encouraged to normatively reference ISO and IEC standards or to

jointly develop standards when appropriate.

GDPR Update

The General Data Protection Regulation (GDPR) (Regulation EU2016/679) is a regulation by which the European Parliament, the Council of the European Union, and the European Commission intend to strengthen and unify data protection for all EU citizens and individuals within the European Union (EU).

The GDPR’s primary aim is to give control back to citizens and residents over their personal data. Because of its extraterritorial aspects, international businesses will be impacted by the regulation.

Goes into effect on May 25, 2018

The GDPR applies to organizations established in the EU and to organizations, whether or not established in the EU, that process the personal data of EU individuals. – IEEE meets these qualifications and is subject to the GDPR.

General Requirement and Test Procedure for High Voltage Lead Exit of Transformer

and Reactor

IEEE Standard PAR

1

China Electric Power Research Institute

1 Background

• Lead exit is an important component in transformer connecting the windings withbushings.

• Lead exit needs to withstandcentralized and asymmetric electric field, as well as different kinds of vibration in limited space, leading to higher technical requirement.

UHV lead exit of transformer 02

EHV lead exit of transformer

031000 kV lead exit structure

• The complex structure and manufacturing process make the quality control of lead exit more difficult than other components in transformer.

1 Background

Failure location statistic of transformer in Israel (CIGRE A2 session paper, 2017)

1 Background• Lead exit is a weak part oftransformer due to the complex structure and toughoperating conditions.

• According to statistics, thefailure of lead exit accounts for 7.4% of the transformer failure in Israel.

• Several failure cases of leadexit have happened in China.(Severe PD, breakdown of disk structure )

Lead exit failure casein China

2 Need for the project

• The unstable quality of lead exit has negative impact on reliability of transformer.

• However, there is currently no international standardspecifying the electrical/mechanical test procedure, also the performance requirement of lead exit.

3 Purpose

• To set up a standard specifying general requirement and electrical/mechanical test procedure for lead exit，to better test and control the quality of lead exit.

4 Scope

The standard applies to lead exit of oil immersed AC transformer/reactor with voltage level of 1000 kV and 750 kV.

The standard specifies general technical requirement, classification and selection principle, electrical and mechanical test procedure and performance evaluating method.

Annex 3 – PAR Proposal on Lead Exits from CSEE

(1) General Requirement

• Electrical

Impulse voltage test

Voltage withstand test

Partial discharge

• Mechanical

Dimension

Resonance frequency after vibration test

(2) Selection Principle

• There are several types of lead exit, categorized by their location.

——Middle lead exit in turret

——Middle lead exit in tank

——Top lead exit in tank

• Selection of lead exit should consider the capacity of transformer/reactor, transportation limitation and winding arrangement.

(3) Test Procedure• Type test (individual):

——Insulation test

——Vibration test

• Routine test

——Electrical test (after assembling with transformer)

——Dimension

——Appearance (whether distorted or layered)

• Special test:

——Mechanical aging test

—— Electrical aging test

—— Thermal aging test

Type Test ‐ Insulation Test• Current Problem: the insulation type test of lead exitis generally implemented when it is assembled in the transformer/reactor, once fail, the test will inflict damage to other components of the transformer.

• Individual Test：equivalent method

• Test Item:

——Pre‐PD test

——Impulse test (lighting impulse, switching impulse)

——Long duration power‐frequency withstand voltage test (953kV/10h, monitoring PD)

Type Test ‐ Vibration Test

• Fixation method

• Sensor layout

• Severity level

• Test Item

——Wide‐band random vibration

——Shock vibration test
